Harold is a security guard for Sandpiper Crossing.
When Jimmy comes back to Sandpiper, Paula tells him that he is banned from entering the premises. She says that they've enacted a new policy in order to protect their residents from unwanted "legal solicitation." As Jimmy argues with Paula, he hears the sound of shredding from the adjacent office. Jimmy manages to talk his way into being allowed to use the restroom, where he furiously scribbles a "demand letter" on toilet paper, informing Sandpiper Crossing of pending litigation against them. He thrusts the "document" at her before he is tossed out by Harold and Gary. ("RICO")
